I had a total of 4 interviews with 7 people: A brief screening interview, a 1:1 interview with the PSE Director, and 2 panel interviews (one with 3 people and one with 2). I followed up with each interviewer with a personalized note after each interview and did not receive a single response. They did not inform me that I was not selected for the position; I had to follow up with them to get that information.
